Abstract
The invention discloses a machinery seal comprising a flange plate; a rotary shaft is arranged in the middle of the flange plate; a static ring is arranged at the periphery of the lower end part of the rotary shaft and between the flange plate and the rotary shaft; a movable ring is arranged above the static ring; an oil seal, a bearing and a fixing assembly are mounted at the periphery of the upper end part of the rotary shaft from top to bottom; and a spring is arranged between the bearing and the fixing assembly. The machinery seal has good leakproofness, cannot add surplus substances to pollute the material, and is small in size and convenient to convey, and a rack does not need to be additionally arranged during practical use, thus facilitating the operation.
Description
Technical field
The present invention relates to a kind of seal arrangement, be specifically related to a kind of mechanical seal.
Background technique
at present, glassed steel reaction vessels is to contain the glass of high silicon dioxide in the prior art, lining is at the internal surface of Steel Vessel, through high temperature sintering and securely adherence becomes composite product on metal surface, it has the stability of glass and the two-fold advantage of metal strength, it is a kind of good corrosion resistant apparatus, existing vesselseals is all with cooling jacket, to pass into cold water and reach cooling effect in cooling jacket, so just have an opportunity to the material contamination in reactor, and this mechanical seal volume and weight is all very large, be inconvenient to carry, in addition, need other installation frame during the actual use of existing mechanical seal, then speed reducer and motor are installed on frame, operation is trouble comparatively.
Summary of the invention
The objective of the invention is the deficiency that exists in order to overcome prior art, a kind of mechanical seal is provided, it does not have cooling jacket, good airproof performance and can not add unnecessary material contaminated materials, the little convenient carrying of volume, do not need to settle in addition frame, easy-to-operat during actual the use.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of mechanical seal, comprise flange plate, and the middle part of flange plate is provided with rotating shaft, it is characterized in that, between described flange plate and described rotating shaft and be positioned at peripheral place, this rotating shaft underpart and be provided with stationary ring, this stationary ring top is equipped with rotating ring; Be positioned at periphery, described rotating shaft upper end portion oil sealing, bearing and fixing-assembly are installed from top to bottom, be connected with a spring between described bearing and described fixing-assembly.
Preferably, described stationary ring cover has O type circle, and is surrounded with the stationary ring pad above this stationary ring.
Preferably, be provided with O type circle between described rotating ring and described rotating shaft.
Beneficial effect of the present invention: have good sealing, can not add unnecessary material contaminated materials, the little convenient carrying of volume, do not need to settle in addition frame, easy-to-operat during actual the use.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described.
Fig. 1 is the sectional view of mechanical seal provided by the present invention;
Numeral and the represented corresponding part title of letter in figure:
1. oil sealing 2. bearing 3. spring 4. fixing-assembly 5.O type circles
6. rotating ring 7. stationary ring pad 8. stationary ring 9. flange plate 10. rotating shafts
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1, a kind of mechanical seal, comprise flange plate 9, and the middle part of flange plate 9 is provided with rotating shaft 10, and between flange plate 9 and rotating shaft 10 and be positioned at peripheral place, this rotating shaft 10 underparts and be provided with stationary ring 8, these stationary ring 8 tops are equipped with rotating ring 6; Be positioned at rotating shaft 10 peripheries, upper end portion oil sealing 1, bearing 2 and fixing-assembly 4 are installed from top to bottom, be connected with a spring 3 between bearing 2 and fixing-assembly 4.
Wherein, stationary ring 8 covers have O type circle 5, and are surrounded with stationary ring pad 7 above this stationary ring 8, also are provided with O type circle 5 between rotating ring 6 and rotating shaft 10.
The invention provides a kind of mechanical seal, have good sealing, can not add unnecessary material contaminated materials, the little convenient carrying of volume, do not need to settle in addition frame, easy-to-operat during actual the use.
It is more than the description to a kind of mechanical seal embodiment proposed by the invention, multiple modification to these embodiments will be apparent for those skilled in the art, General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, realization in other embodiments.Therefore, the present invention will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
Claims (3)
1. a mechanical seal, comprise flange plate, and the middle part of flange plate is provided with rotating shaft, it is characterized in that, between described flange plate and described rotating shaft and be positioned at peripheral place, this rotating shaft underpart and be provided with stationary ring, this stationary ring top is equipped with rotating ring; Be positioned at periphery, described rotating shaft upper end portion oil sealing, bearing and fixing-assembly are installed from top to bottom, be connected with a spring between described bearing and described fixing-assembly.
